From Scientific American:
The biggest breakthroughs in how we make things lie not in the technology to manipulate materials but in the materials themselves. Such is the thinking behind "4-D printing," an experimental approach to manufacturing that expands on much-hyped 3-D printing processes. Instead of building static three-dimensional items from layers of plastics or metals, 4-D printing employs dynamic materials that continue to evolve in response to their environment.
